Amr or Lyra?

Hello I am studying the functioning of this codec and I would like an exchange of views:
In terms of computational resources, library weight and performance is it better to record audio in .amr or .lyra?

In the sense, by registering with .amr at a low level you can avoid using external libraries and therefore you can keep the application clean, furthermore the registration with amr is computationally light, would the lyra be too?

Thanks!
